Embodiment 1

[0057] Example 1: Indoor joint toxicity study on Tetranychus cinnabarinus compounded with Chuanxiong oil and rotenone

[0058] 1.1 Materials and methods

[0059] The pests tested: Tetranychus cinnabarinus ( Tetranychus cinnabarinus Boisduval), Northwest Agriculture and Forestry University, Greenhouse Farming of Pollution-free Pesticide Research Service Center.

[0060] Drugs for testing:

[0061] A. Ligusticum chuanxiong oil, provided by Guangxi Hengxin Spice Company, with a ligustilide content of >35%.

[0062] B. Rotenone was provided by Guangxi Xerox Agrochemical Co., Ltd., and the active ingredient content was ≥98%.

[0063] 1.2 Determination method

[0064] Indoor bioassay on pest mites was carried out by dipping slide method. Cut the double-sided tape into two centimeters long and paste it on one end of the microscope slide, and then tear off the paper on the glue. Select a healthy adult mite, pick it up with a small brush, stick its back on the glue, and pay...

Embodiment 2

[0097] Example 2: Indoor combined toxicity test of Chuanxiong oil and rotenone against apple yellow aphid

[0098] While carrying out the above research, the applicant used the apple yellow aphid as a test insect, adopted the method and procedure of "Example 1", systematically tested the synergistic effect of the mixed use of Chuanxiong oil and rotenone on aphids, and obtained a result similar to that of Example 1. Similar conclusions, that is, the combination of Chuanxiong oil and rotenone has a significant synergistic effect on the apple yellow aphid. This example only gives the test results of the co-toxicity coefficients of the four compounding agents on the apple aphid.

[0099] ,experiment material

[0100] Aphids tested: apple yellow aphid ( Aphis citricola van der Goot), collected from the Fruit Tree Experimental Station of the College of Horticulture, Northwest A&F University.

[0101] Drugs for testing:

[0102] Ligusticum chuanxiong oil, provided by Guangx...

Embodiment 3

[0112] Example 3: Preparation of 30% Chuanxiong Oil·Rotenone Environment-friendly EC

[0113] At 20-25°C, take 30 parts of Chuanxiong oil and rotenone, the compounding ratio of Chuanxiong oil and rotenone is 14:1, add 10 parts of azone, 20 parts of machine oil, and 3 parts of dodecyl in sequence on the basis of the above mixture Sodium benzenesulfonate and 7 parts of octylphenol polyoxyethylene ether, ethyl acetate make up 100%, and stir at a stirring speed of 800-1000 rpm for 10-30 minutes to prepare 30% Chuanxiong·rotenone EC.

Abstract

The invention discloses a plant source synergistic compound aphicide and acaricide containing rotenone, and the prepared plant source synergistic compound acaricide is prepared by compounding Szechuan lovage rhizome oil and the rotenone as main active ingredients with auxiliaries, wherein the weight ratio of the rotenone to the Szechuan lovage rhizome oil is (8:2)-(7:3), and the preparation form can be oil emulsion, microemulsion and aqueous emulsion. The plant source synergistic compound aphicide and acaricide has higher control effect in fields for aphis citricola, cabbage aphid, macrosiphoniella sanborni, aphis gossypii glover and other aphids on fruit trees, vegetables and flowers, simultaneously has good control effect for tetranychus viennensis zacher, tetranychus cinnabarinus andother mite type pests, and has great application and popularization value on organic crops.

Description

technical field [0001] The invention belongs to the technical field of biopesticides, and in particular relates to an aphidicide and acaricide with two plant-derived substances, chuanxiong oil and rotenone, as active components. It is mainly used to control aphids such as apple yellow aphid, cabbage aphid, chrysanthemum aphid and wolfberry aphid, as well as harmful mites such as hawthorn Tetranychus, Cinnabarinus and Tetranychus urticae. Background technique [0002] Acarids (mites) belong to Arthropoda (Arachinida), Arachnida (Arachnida), Acari subclass (Acari). According to its economic significance, it can be divided into two categories: medical and animal husbandry acarids and agricultural pest mites. Among them, the important agricultural pest mites are concentrated in 6 families of Acariformes (Acariformes), the most important pest mite is Tetranychus mites, followed by Hypophyllus mite, Gall mite, Nematode mite and Acarid mite. Among them, spider mites are the large...
